Known in his high school as "Calamity", the "Lord of Catastrophe" Lin Xiongchen is a high school kid who's been bogged down by bad luck for most of his life. Because he is known to "attract bad luck to those who get close to him", he is ostracised by his classmates, which leads to him mastering the incredible ability of reflection which helps him evade all forms of danger. In a situation both thanks to fate and sheer coincidence, Lin Xiongchen finds himself possessed by a Demonic Lute one day. However, the curse of bad luck is simply too overwhelming, even for the demon. In order to survive, the Demonic Lute has no choice but to teach Xiongchen ways to turn the wheel of fate around to his benefit.
